Abstract
A printer includes an opening in communication with a tray receptacle for receiving a paper tray. The printer further includes a pick roller assembly; a separator shaft including a first separator roll; an arm structure connecting the pick roller assembly to the separator shaft and enabling a pick action to be imparted to the pick roller assembly; and a feed roller coupled to the separator shaft. A removable media tray is positioned in the tray receptacle, holds a stack of paper sheets and includes a second separator roll and a gear that couples the second separator roll to the separator shaft. A controller causes (i) a rotation of the separator shaft and separator roll in a first direction to enable a paper pick action and to simultaneously rotate the second separator roll to enable a paper sheet separation action, and (ii) a rotation of the separator shaft in a second direction to disable the pick action and to rotate the feed roll to accomplish a paper feed.
